Phase-Cut Dimmable Flyback or Buck-Boost Current Control with Active PFC for LED lighting DESCRIPTION The TS19320CS is a phase-cut (TRIAC) dimmable Constant current accuracy <±5% Flyback or Buck-Boost w/o photocoupler Good dimmer compatibility for 120/230VAC Lamps Boundary-mode PFC operation Built-in active power factor correction High voltage (500V) startup circuit Open-LED demagnetization (DMG) protection VCC over-voltage protection (OVP) Over-temperature protection (OTP) Shorted-LED Protection Cycle-by-cycle current limit Gate drive voltage clamping Compliant to RoHS Directive 2011/65/EU and in accordance to WEEE 2002/96/EC. ● Halogen-free according to IEC 61249-2-21 constant current control IC with active power factor correction isolated or non-isolated AC-DC LED lighting control. The TS19320CS is configurable as an isolated, primary-side-regulated Flyback controller or non-isolated Buck-Boost converter. It is compatible with many types of TRIAC dimmers including leadingedge and trailing-edge. The IC achieves a high power factor and low total harmonic distortion (THD) and guarantees constant current accuracy to <±5% using Boundary Conduction Mode (BCM) operation. The TS19320CS has built-in protection circuits such as gate voltage clamping, over temperature protection by current degeneration, VCC overvoltage protection and system output open/short circuit protection. APPLICATION ● LED lighting ● Down lights, Tube lamps, PAR Lamps, Bulbs Notes: MSL 3 (Moisture Sensitivity Level) per J-STD-020 TYPICAL APPLICATION CIRCUIT Flyback Converter

TAIWAN SEMICONDUCTOR TS19320CSTaiwan Semiconductor APPLICATION INFORMATION Pin Definitions (Continue) DMG The Output voltage is reflected by the auxiliary winding (NAUX) voltage of fly-back transformer, the DMG pin can sense output information to depart from start up voltage (Vo_stR) and protect voltage (Vo_ovp). When the DMG sense voltage under VO_STR, the circuit will work on short circuit protection, fSTR=1/tSTR. When the DMG sense voltage over VO_OVP, the circuit will work on over voltage protection, it will latch out until VCC goes below Vcc_off- Nsec Rdi + Rd2 VO OVP = x Vovps x Where...
